What Is Copper Smelting? (with pictures) - Info Bloom

Refining copper results in three and a half times as much waste as the amount of copper produced. This waste is not only in the form of solids that must be disposed of or recycled, but also sulfur dioxide gas. Sulfur dioxide is a significant air pollutant, particularly notable as a precursor to the production of acid rain.

Generally, copper is floated firstly and then sulfur. The content of pyrite in dense massive copper-bearing pyrite is quite high and high alkalinity (free CaO content> 600～800g/m3) and high dosage of xanthine are often used to suppress the pyrite. There is mainly pyrite in its tailings with few gangues, so the tailings are sulfur concentrates.
